Life changing!

Jess M

My beauty therapist added this to my skin routine and it has been the best! I introduced it slowly as recommended and now can't wait to use it every night. It smooths and softens my skin and is quick to jump on pesky blemishes.

Most Helpful Criticism

Not the same as previous batch


I was so happy with this product the first time I had it that I decided to buy it again. However, the new (and exactly the same name, strength etc) product keeps giving me a strong irritation around the eye area. Not sure what’s happened there, especially since the first batch was perfectly fine, but I am very disappointed given the price point.
  1. Best retinol

  3. Ok. Yeap. I get the hype now.


    The difference between using Medik8 on my skin has been astounding. This retinol is ..wow. Genuinely noticing improvements in my skin texture and appearance. Word of caution though, do not overuse it and introduce it gently otherwise it will sensitize the skin. Patience is very much key with this product. I'm still only using it max twice a week, and happy to continue for the foreseeable future be...

  4. Amazing set of retinals!!!


    I have been using the Crystal Retinal range (as a step up from The Ordinary’s retinol) and it’s significantly improved my skin’s texture, bounce, slightly minimised lines and I rarely get hormonal acne now. I started with Crystal Retinal 3 and moved up to the 6 after I finished the tube. I started the 6 by using it every 3 nights for the first 2 weeks, then stepping up to every second night, and I...

  5. My security blanket


    I am obsessed with this vitamin A, I always make sure I have a new tube waiting when I get close to the end of my current one as I refuse to go without. The formula is a beautiful light creamy consistency with a light fresh and pleasant scent (think baby powder meets soft clean antiseptic type smell) If you’re umming and ahh-ing on whether to give this a shot, I highly recommend it to anyone who...

  6. Go to retinol


    Easily my favourite retinol I’ve tried so far, has done wonders for my hormonal acne and it smells like heaven to boot!
  7. Good Anti-aging product


    Changed from Murad retinol A to this one, I like both of them. Different from Murad, Medik8 retinol gives you a matt finish. I feel my pores has become smaller and my skin is smoother
  8. Best Retinoid


    This product is the best retinoid I have tried. As it is retinaldehyde, it only requires the skin to undertake one process to convert it to retinoic acid. I have seen a significant difference in decreasing blemishes and post-inflammatory hyperpigmentation. I have sensitive skin and it has not not dried my skin or caused redness, however my skin is very tolerant to vitamin A. Will be repurchasing...

  9. Good, gentle retinol


    verified purchaser
    I found that this retinol product is quite gentle on the skin and I'm enjoying it as an upgrade from the -TR line. The smell was a bit funny at first, but I quickly got used to it.
  10. Can’t tell any good changes in my skin!


    After reading all the good reviews i was really excited to give it a try but I’m really disappointed!
    It didn’t met my expectations! After using it for a good time i haven’t seen any improvement in my skin.
  11. Best retinol I’ve used


    This is the most effective and non irritating retinol I’ve used! I have fine lines and oily skin that breaks out easily, I’m in my mid 30s. This product prevents pimples and I think that’s down to not containing silicone (which make me break out). I have noticed a brighter and more youthful complexion, and my forehead lines have softened. I like the texture as it’s lighter and more moisturizer-lik...

  12. Visible Difference


    I got introduced to this product at my skin clinic and was my entry into retinols. It has really helped with the texture and fine lines along with keeping my acne at bay.
  13. Amazing results


    I went from the La Roche Posay retinol (which is lovely) to this and the difference was visible within a week. I had no sensitivity and after a month I've moved up to using it every night. My fine lines are improved and my pigmentation is disappearing, my skin has never looked better. Worth every cent.
  14. Good product


    I bought this product to help with fine lines and uneven skin tone. I have been using it 4-6 times a week for about 4 months and it has only just run out. I went to using the number 6 from next to no previous use of vitamin A and had no skin reactions after following the instructions.
    I can notice my skin tone looks more even and younger. I have been getting complements from friends as wel...

    My new go to vit A serum!! I have used Medik8 for a long time and finally ran out of one of their older retinol formulations so I snapped this up after hearing great things about it. I LOVE the texture, it absorbs beautifully and the whole experience is lush. I can't recommend this enough. That being said, I probably should have started with the Crystal Retinal 3 and stepped up to this one after a...

  16. so good!


    I love this product! I've been using it for about 6 months and am about 2/3 through the tube. I use it 2-3 times a week. I started with Crystal 3 before Crystal 6 and have had no issues with irritation. I LOVE that there are no silicones in this product (as they congest my pores). I'm prone to breakouts and therefore can have some pigmentation post-breakout. I think this product helps keep my ski...

  17. Fav


    I love this product, although you do have to work your way up to this level of retinal. I started at the 3 and now using this! Love it
  18. Love this


    Love this retinol, super smooth to go on. no weird smell.
    and great that there is option to move up within the product range
  19. Staple product


    I highly recommend this product. I was orginally using the retinol 3tr. After liking the results I decided to step up to the retinal 6. Really gentle on the skin, not drying, nice fragrance. After finishing this I will move up to the retinal 10.
  20. Lovely formula


    I started with Crystal 3 as I was a bit scared to go too hard on retinol. Never had a single issue of irritation or redness or flaking with Medik8. This is a lovely formula, I’ll often skip moisturiser afterwards. I will move to the crystal 10 after this though
  21. Nice formulation


    I’ve tried retinol before but I wanted to up my game. I was so surprised how nice the formula feels on. I still get a bit of dryness but I think that’s just the retinal working. I’ve only start using it but can notice the different. I’m so glad that I bought this and really raised my retinal game!
  22. Step by step


    I liked this product. I used it every other night without any skin irritation. My skin tolerated it well. previously I had used a Skinceuticals Retinol 0.3 ... maybe it help.
    in any case, it works and it seems to be a good alternative for retinol sensitive skin
  23. working my way up to the highest strength


    This was a nice upgrade from The Ordinary retinol that I was using (that one was very oily). I've not yet experienced any flaky skin or irritation from retinol and I'm going to purchase the next strength up next time. I like that it glides on really smoothly. I follow with a moisturiser after.
  24. Fast results, minor purge


    So I purchased this in hopes to clear my post pregnancy skin. It worked amazing, it glides nicely, but not moisturising, so you will need a moisturiser on top of this. I did purge after the 2nd week introducing it, but I did expect it since I hadn't used a rentinoid cream for such a long time. I'm still using it, it smells nice and powdery but its very potent.
  25. Fantastic option before prescription


    This is a fantastic retinol option if you don’t want to or can’t get prescription strength. I found its consistency to be quite hydrating and you don’t need a lot. It’s quite strong and you definitely need to take your time easing into it.
  26. Exceptional


    Already a fan of Medik8, i stepped up in strength to this product & was even more impressed than expected! I use it 3-4 times a week as a staple in my fight against aging. I have normal to oily skin prone to breakouts & this product helps keep everything under control - highly recommend
  27. great quality


    In love with retinal, I have really noticed a difference with wrinkles and fine lines. This brand is good quality, a new must have
  28. Improved skin texture


    Have used it for about 2 months.
    At first few weeks, it made my skin a bit red and irritate but that is how it work. Use with moisturizer helps to reduce the dryness and redness.
    After 1 month, my skin looks fresher, smoother and healthier but the pigmentation is not improved.
  29. Must have


    If there is one thing u need in your skincare regime it’s a good quality retinal.
    After using a retinol product for years I made the switch and my skin has never looked or felt better
    I feel like I’ve dropped 5 years off my appearance with less fine lines and pigmentation
  30. Fixed cystic breakouts


    I have had problems with deep cystic breakouts for years (I’m 24) and tried too many products and skin routines. I ended up coming to the conclusion it was hormonal and had to do with my contraception so there was nothing that could be done about it. I originally bought this for fine lines and prevention against ageing but it completely cleared my skin up too. I’ve had no cystic acne for months an...

  31. Fab Retinol!


    This is great! Moved to this from a 1% serum retinol and it is so gentle and hasn't given me any flakiness. I love Medik8 and have never used a bad one (and I have a lot of their products!)
  32. Love this!


    First time using Retinal & I am loving it! No irritation at all & my skin looks amazing! Recommend this brand 100%. Can’t wait to try more Medik8 products.
  33. Effective


    I have normal to dry skin. I have been using retinol products for about 14 years. I wanted to try a retinal product to see how it worked. I really like this one. A small amount smooths over my whole face and neck. Any left over residue I put on my chest and the backs of my hands. I did experience slight sand paper like peeling because I used it every night. I didn't mind. The peeling lasted a w...

  34. works!


    not irritating at all. Works well and my skin feels fresh the next morning
  35. Battle Scarring


    My favourite part of my skin care routine! I have been using this product for well over a year now, and it's help reduce my stubborn scars on my cheeks that I thought would never fade away. The only product that has truly helped, I will buy this product over and over again!
  36. Smooth as butter


    After using oil based retinol previously I was a bit surprised when i saw the texture of this one. Its very buttery and smooth. I used it sparingly as it glides quite well across the skin. I have to admit I was very skeptical as i didn't really feel like it did much straight after applying it but when i woke in the morning my skin was the smoothest its ever been. Definitely worth the money!
  37. Love this product


    I started using this after using a tube of the Retinal 3. No irritation and I have noticed some of my forehead wrinkles, which were quite prominent, have improved. Will repurchase.
  38. lovely retinol product


    Great product ..leaves skin feeling smooth and looking bright ...no irritation so far .. expensive but worth it I think ..love it
  39. Faboosh


    One of the Best Retinal’s I have tried - I have tried a lot - did not irritate my skin and noticing clarity in my skin already after one weeks use. I have been able to use two days in a row with one nights breaks! So far so good - Up there with Verso Night Retinol but not as pricey X
  40. Cream consitency


    This product is gretat as I find that it is very gentle on the skin. However when purchasing I did not realise this was a cream consistency I was hoping for a serum texture. I will use this all up and move onto the Retinol 6TR Advanced 0.6 as I was advised by th customer care team this is serum texture
  41. Easy step up in retinol


    Being reasonably new to retinol, I stepped into the crystal 6 from the medik8 night ritual cream. I’m half way through and have had no irritation, sensitivity or dryness. The morning after using I have plump and fresh skin and works well under all my other products (aspect and ASAP)
  42. Excellent retinal


    This has never irritated my skin from first use it has been excellent. It has minimised my acne and has helped with some small fine lines I had. My skin looks so much more healthier and glowy
  43. Great retinol choice


    I chose this retinol on the basis of many people recommending it. I'm 24 years old and bought this product to help smooth skin, help with pigmentation and breakouts. I havnt seen a result so far but it's early days. However I am loving the consistency. An orange cream that skins into the skin quickly. My skin is feeling slightly dry from its use, but that's also the result of using retinol and I u...

    I was recommended this by my beauty therapist. I saved so much money buying it here on Adore Beauty as opposed to purchasing it at my salon. Let me tell you, I have been using this for two days and my skin is already looking more even in tone and seems to be looking slightly less red. I have acne scarring and uneven skin tone and have tried every potion and lotion on the market. Im impressed alrea...

    I am a big fan of this product. I am currently struggling with acne and fine lines. This product has worked wonders for both and has made a difference to some of my pre existing acne scarring. This product has been completely non irritating and made an overall improvement to all of my skin concerns (pigmentation, texture, scarring, acne, fine lines, enlarged pores). I would recommend starting with...

  46. So far so good


    I'm a regular user of retinol so was interested to hear about the difference between retinal. I've only used it twice since getting and it looks like its smoothing out my skin - I probably should have bought the next one up - Retinal 10.
  47. Must always have a back up


    This product has transformed my skin.
    I have been using cosmeceutical grade retinol for a few years now but none have made such a drastic change to my skin as this.

    When first moving to this product from medik8 retinol 3 - I did experience 2 weeks of peeling skin even when using it every second -third night. Once my skin adapted it has looked so much brighter with a healthy glow...

  49. Effective and gentle


    I have been using this product for almost 4 months now and I am very impressed with the results. It has even out and brightened my skin tone to the extent I am comfortable going out without any base makeup. By gradually phasing in this serum and buffering with a moisturiser afterwards have alleviated the side effects commonly associated with retinol. I experienced no flaking or peeling whatsoeve...

  52. Love it


    I really like the crystal retinol range from medik8. It's allowed me to easily step up to a higher level with zero irritation due to it's special micro encapsulated formula. They say this is better than retinol as it's got one less conversion to do this product doesn't irritate me at all. Start on the 3, move to the 6 then up to the 10.
  53. Holy grail!


    I was hesitant to start a retinol/retinal serum but this is a godsend! Forehead wrinkles have disappeared and absolutely no skin irritation!
  54. Love


    Medik8 is one of my favourite high end brands. I think medik8 make the best retinol products on the market I am very impressed.
  55. Liquid Gold


    This stuff is amazing, the best skincare purchase I ever made. I had never noticed much difference to my skin, no matter what I used on it, until I tried this! It has never irritated my skin, and my skin is usually prone to redness and large pores. I always had to wear foundation to cover the redness and since using this product I can go foundation free. Honestly, if you buy just one expensive ski...

  56. Better than normal Retinol


    This serum has a very nice texture, and I found it to be better than normal retinol serums, as it acts faster, and didn't cause any irritation (my skin is pre-conditioned with retinol).
  57. Good results


    I used this product for a while before switching to the retinal 10. It’s really good as an intro to retinal products but I found the texture a bit lumpy and took a while to absorb. Also the pump doesn’t dispense an even amount consistently which is annoying.
  58. Potent but gentle retinol


    I’ve tried a few different retinol products now I’ve hit mid 30’s and I’ve started to see some signs of ageing, nothing beats this one. Now I’ve found it I’m not changing it. It’s helped with skin turnover and my skin feels fresh and vibrant but it’s also gentle.

    Starting retinol my skin was pretty awful for 4-6 weeks (red, acne) but it has really settled down now and I am happy with...

  59. A must for 40+


    I've been tinkering with retinoids for a little while, this is a good one. I've gradually increased the usage to a couple of times a week and have noticed an improvement to my skin. It does need moisturiser afterwards though, but that's all. Would definitely repurchase.
  60. Amazing


    So happy I purchased this. I was concerned my sensitive skin would react poorly, however reading the reviews encouraged me to try. Never has my skin felt so smooth, nor wrinkles softer. I recommend trying this as an introduction to retinol and a sound skin care routine.
  61. Fave


    Great retinol cream - best I’ve had
  62. Working but not a fan of added synthetic colour


    I purchased this after having previously used Medik8's retinol 3TR. I have really sensitive skin and was worried the higher retinol concentrate would irritate - but so far no reaction at all. I do have pre conditioned skin regarding retinol though. The only thing I would say is I'm not really a fan of the added orange colour and vanilla scent, but it does seem to sink in quickly and provide not...
